Answer:

the equation of the line is:

y = 1/2x + 3/2

Explanation:

given points are:

x1, y1 = -7, -2

x2, y2 = -3, 0

equation of the line is:

y = mx + b

where slope, m = y2 - y1 / x2 - x1

= 0 + 2 / -3 + 7 = 2/4 = 1/2

let's take x1, y1 as x, y co - ordinates to find the value of constant, b

-2 = 1/2(-7) + b

-2 = -7/2 + b

b = -2 + 7/2 = -4 + 7 / 2 = 3/2

thus, the equation of the line is:

y = 1/2x + 3/2
